Well done! I have the same dilemma. I reallly like my existing colour, silverlake as per the avatar but it is getting quite common. There must be at least 5 or 6 cars in the same colour now. Still my new Aero is scheduled to be the first produced in 2009 so I have some time as well to decide on colours.
Ichanged my mind about 2-tone. If I could get it done like the 2-tone on the old Bentley's etc where the wings and upper body are one colour and just part of the lower body is another I might still go for it.
I do have a cunning plan for the interior though!
